3” Aluminum Swing Check Valve

Swing Check Valves are designed for maximum flow of air or dry products with minimal pressure drop. The poppet assembly is self-aligning to assure even sealing on the raised vertical seat. The poppet assembly can be easily removed for replacement.

Features & Benefits

More Air Flow – A high flow valve means less pressure drop and faster unloading rates.

Less Heat Build Up – Due to the spherical design of the Knappco 3" Aluminum Swing Check less turbulence is created in the air stream, reduces back pressure, provides smoother air flow reducing heat build-up and wear and tear on the blower.

Easier to Rebuild and Service – The poppet and top lift out as a single unit allowing serviceable parts to be easily and efficiently accessible. Field maintenance is possible without removing valve from air line.

Optional Seal Tabs – To ensure load integrity.

Embossed Casting Area – Provides an area to personalize each valve.

Light Weight – Aluminum, heavy duty construction.
